Catan Travel Box

I hate everytime I take Catan somewhere all the pieces mess during the travel in the original box. So I made a travel box using the great rugged box design from Whity I made two version of the top, one to print multicolor with AMS and another multipart to print letters on a separete plate. It's important to calibrate tolerances so letters fets correctly. To assembly just need x6 M3 30mm
